Maple Some very basic Maple help (numtheory)

[dkotschessaa]

This is EXTREMELY basic. I am using maple to run a Pohlig Hellman algorithm to solve discrete logs.

If I use ifactor to get a result, i.e.


> ifactor(p-1);

(2)³ (5)

How do I assign the output of these different factors to some other variable so I can use them elsewhere?

Not sure exactly what you're asking but I found this Maple Intro pdf that may help.

I hope you don't mean:

> y=ifactor(p-1)

so that y is the 2^3 * 5 value.

Not quite. I want to assign the values separately. i.e. I want to assign the 2^3 to one value and the 5 to another. (actually just the 2, I don't need 2^3, but that would have been my next question).

so the ifactor() returns an array so if you say y=ifactor(p-1) you'll get an array of one or more factors.

To iterate use a for loop and use the Size(y) to get the number of elements for the loop or better yet

use for yy in y do ... od

That's a step in the right direction, thanks.
